ADJUSTABLE HANDLE-BAR FOR BICYCLES.

SPECIFICATIONIforming part of Letters Patent No. 606,192, dated June 28, 1898.

Application tiled February 23, 1897. Serial No. 624,526. (No model.)

means whereby the handle-bars of a bicyclev may be adjusted pivotally upon their inner [L: ends and vertically in the steering-head of the bicycle. Y

It is desirable that there be a wide range of adjustment in a bicycle handle-bar for the reason that riders vary greatly in taste, one zo rider preferring very low handle-bars and another very high ones. For this reason it is preferable that the handle-bar as a whole be adjustable bodily in the AVertical direction and also that the respective members of the 2 5 bar be adjustable pivotally upon their inner ends, so that the angle of the said members to the steering-head may be varied and the range of adjustment greatly increased. It is my desire to provide improved means for both 3o of these adjustments; and to such end my invention consists in certain novel features of construction, which will be fully described below and closely dened in the claims at the end of this specification.

For the purpose' of illustrating my invention I have shown in the drawings presented herewith two figures, of which- Figure l is a front elevation of a handlebar embodying my invention; and Fig. 2 is a 4o diametrical longitudinal section of the same in a plane parallel with the surface of the paper in Fig. l, the outer ends of the handlebars being broken away in both figures to enable the remainder to be drawn upon a larger scale than would otherwise be possible.

d top in a T-shaped head Bv', upon the opposite sides of which are pivoted the respective members B2 B3 of the handle-bar by means of pins Z) b. The inner ends of these members 'are each formed in the shape of an arc about the pivot-pin and provided with ratchet-teeth b2 b5. Across the top of the T-shaped head is a long washer O, having its opposite ends c c concave upon the under side and pro- 6o vided with teeth c2 c3, adapted to engage with those upon the inner ends of the members B2 B3. Said washer also has downwardly-projecting lugs c4 c5, and'sockets b4 b5 are provided in the T-shaped head to receive said Vlugs and assist in preventing horizontal movement of the washer in any direction. The Washer and T-shaped head are respectively provided with central holes c6 b, and a bolt D extends through these holes and is provided 7o with a nut d at the top and at the bottom, which projects slightly from the lower end of the shank A. It has a tapered head d', adapted to wedge upward into the shank B. The

lower part of the latter is preferably slit to 7 5 allow it to expand within the steering-head A.

The bolt D has a notch cl2, and a pin 137 is passed through the T shaped head and through this notch to prevent the bolt from turning and from falling down into the steer- 8o ing-head when the nut CZ is removed.

In operation the tightening of the nut d lwedges the tapered head CZ upward into the shank B, firmly Awedging the latter in the steering-head A, and at the same time draws the long washer O downward and secures the 4opposite members or handles against pivotal movement upon the pivot-pins. The Washer O is slightly crowned, so that the tightening ot the bolt springs the ends down upon the 9o ratchet-teeth, providing for the taking up of any wear and also insuring a close engagement with said teeth to prevent any looseness their inner ends with ratehet-teeth, a long washer extending from one of said handles to the other and provided at its ends with teeth adapted to engage With said ratchet-teeth and a bolt extendin g through said Washer and shank, said bolt being provided at the top with a nut and at the bottom with a tapered head adapted to expand the shank whereby the tightening of the nut upon the bolt secures the handles upon the shank and the shank in the steering-head; substantially as described.

2. The combination With the steering-head, A, of a handle-bar consisting of the shank, B, having a Tshaped head, B', and the pin, D7, the handles, B2, B3, pivoted in the head and having ratchet-teeth upon their inner ends,
